### Symphony Canvas — Native Multi-Prompt AI Canvas & Autonomous Orchestration

    Symphony Canvas is a high-performance, Rust-native visual canvas built for engineering, chaining, and
    comparing multiple AI prompts side-by-side without browser overhead.

    #### 🎯 Problem & Inspiration
    Traditional single-window chat interfaces force developers and creators into repetitive manual
    cycles—copying outputs between prompts, losing track of intermediate experiments, and struggling to
    orchestrate multi-step LLM pipelines. Existing visual workflow tools are typically bloated Electron/web
    wrappers that lag under load and lack deep native OS integration.

    #### 💡 Solution & Key Features
    - **Zero-Lag Rust GUI:** Built entirely with Rust (`egui`/`eframe`) using multi-threaded OS background
    workers over `mpsc` channels—delivering a lightweight, responsive desktop UI that never freezes during
    heavy concurrent inference.
    - **Topological Prompt Chaining:** Connect nodes intuitively with directed links. Downstream nodes
    automatically ingest upstream outputs with cycle prevention and topological ordering.
    - **3 Batch Run Modes:** Execute workflows via `Parallel` (simultaneous runs), `Sequential`, or `Chain`
    execution.
    - **AI Blueprint Generator:** Transforms a single natural language description into an end-to-end
    multi-node canvas pipeline (up to 12 auto-wired and laid-out nodes).
    - **23 Run Modes & Agentic MCP:** Combines direct LLM calls with custom Python execution, media nodes,
    and MCP (Model Context Protocol stdio) autonomous agents capable of dynamic tool calling.
    - **Real-World Notification Loop:** Native scheduling and automated completion alerts dispatched
    directly to Telegram, Discord, and WhatsApp.
    - **Privacy & Security First:** Session API keys are stored in volatile memory only by default, ensuring
    enterprise-grade credential security.
